micro-reaction v0.1.2

one extremely simple observe state library, it's small, but strong.

Motivation

The project is inspired by observer-util and wana, but they is too large and not cleary read, so I refactor it. to be simple and better learn.

Install

npm install --save micro-reaction

Usage

Nested properties

import { observable, observe } from "micro-reaction";

const ob = observable({
    a: {
        b: 1
    }
});

observe(() => console.log(ob.a.b));

// logs: 1
// logs: 2
ob.a.b = 2;

Dynamic properties

import { observable, observe } from "micro-reaction";

const ob = observable();

observe(() => console.log(ob.a));

// logs undefined
// logs 2
ob.a = 2;

Arrays
